cal = UpdateAmbientSensor(cal,new_ambient_sensor,[ADD])

Update the ambient light used in the conversions. The
value for new_ambient_sensor should be passed in the
same units as defined by T_sensor in the call to
SetColorSpace.

If flag ADD is true, passed ambient is added to current
value. Otherwise passed value replaces current value.
ADD is false if not passed. Use caution when setting ADD
true – if the ambient is changing during the experiment
you typically don’t want to keep adding multiple times.

If instead you want to update in the measurement units,
call UpdateAmbient instead.
